When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
Solve -6c + 3c = c - 8z + 7 for c in terms of z.
| 1\(\frac{2}{3}\)z + \(\frac{2}{3}\) | |
| -14z - 8 | |
| 1\(\frac{4}{7}\)z - 1 | |
| -7z - 4\(\frac{1}{2}\) |
